Hi Mitch,
It could be a couple of things. There might be something that has come loose in the lamp itself. Sometimes glue softens from the heat on lamps that are not well made. Other times it’s a loose part in the lamp. Also check your filters to see of they need cleaning. If it was the ballast you would have noticed the image flickering or the color disappearing. We have heard of some generic lamps givng off a strange buzzing sound as they age. Hope this helps.

Hi Steve,
Something else was having the same issue and it turned out the sensor of the lamp door was damaged. Check that the screws to hold the lamp door are still tight and that the door is snug when shut. A lamp cover that is loose won’t let the projector fully turn on. So try that first. The only other thing I can think of is that it might be your ballast wheel that has gone. How old is the projector?

Hi Ryan,
Interesting they both had the same issue with the door sensor being loose. Maybe this is a design flaw. Glad you were able to get both of them working. I will mention this solution to other people and add it to the list of things to check. Thanks for sharing this!

Hi Ryan,
Good detective work! Let me know what happens with the second projector.

Thanks for your reply Shelagh. I replaced the lamp with genuine epson lamp. But still it is not turning on.

It turned on once after few tries but after I unplugged it and plug it again it is not turning on but makes beep sound once.

So Ia have a conclusion to all of this. the short answer is both have been fixed and now run. The main issue seemed to be that the door sensor on both had broken in a way that was keeping it from actively reading when the lamp door was closed. (The plastic piece that the screw attached to broke off.) I super glued the fixture in both units. One worked right after I did that. With the other (which was the first one I messaged you about) I opened it up and kind of cleaned it out even though it didn’t really seem to be that dirty. I also detached and reattached all the wires inside. Though I’m not really sure what was wrong I also got this one working. My last reply was deleted so hopefully this one goes through if anyone in the future needs to resolve this problem.
